👨‍🍳 步骤

1. 1

   Grease and flour a cake mold (ring mold or loaf pan).

   💡 专业技巧: Ensure the mold is well-greased to prevent sticking.
2. 2

   In a large bowl, whisk together the eggs and sugar until pale and fluffy.

   ⏱️ 5 minutes
3. 3

   In a separate bowl, whisk together the flour and baking powder.

   💡 专业技巧: Sifting the flour can help create a lighter cake.
4. 4

   Gradually add the milk, melted butter, vanilla extract, and lemon zest (if using) to the egg mixture, mixing well.

   💡 专业技巧: Add liquids slowly to avoid deflating the egg mixture.
5. 5

   Add the dry ingredients to the wet ingredients in batches, folding gently until just combined. Do not overmix.

   💡 专业技巧: Overmixing can lead to a tough cake.
6. 6

   Pour the batter into the prepared cake mold.

7. 7

   Steam the cake in a preheated steamer or a pot with a tight-fitting lid over simmering water for 40-50 minutes, or until a skewer inserted into the center comes out clean.

   ⏱️ 45 minutes

   💡 专业技巧: Ensure there is enough water in the pot and that it doesn't boil dry. Cover the lid with a kitchen towel to prevent condensation from dripping onto the cake.
8. 8

   Let the cake cool in the mold for 10 minutes before inverting it onto a wire rack to cool completely.
